When Fëanor's half-brother Fingolfin came upon the battle, not knowing the cause of the conflict, he joined on the side of the Noldor. Thus the Teleri were defeated, and many of them were killed in that battle: an act by the Noldor that came to be known in infamy as the Kinslaying.

After the battle, Uinen's grief was so great that a storm came up and wrecked many of the captured ships, but nonetheless the victorious Noldor escaped with a small fleet and made their way northwards away from Alqualondë and towards the coasts of Middle-earth.
